I think most of the important stuff on the Internet has been built. There will be continued innovation, for sure, but the great problems of the Internet have essentially been solved.

I think that's an important thing to do, to really pay attention to negative feedback, and solicit it, particularly from friends. This may sound like simple advice, but hardly anyone does that, and it's incredibly helpful.

I started SpaceX with the expectation of failure.

You shouldn't do things differently just because they're different. They need to be... better.

I think that's the single best piece of advice: constantly think about how you could be doing things better and questioning yourself.

I think it's very important to have a feedback loop, where you're constantly thinking about what you've done and how you could be doing it better.

I could either watch it happen or be a part of it.
